CEHO Power Releases Full Range of Oil-Immersed & Dry-Type Transformers for Global Power Distribution Projects

Lead

As a high-tech manufacturer specializing in medium & high voltage power distribution equipment, CEHO POWER TECHNOLOGY GROUP CO.,LTD. (CEHO) launches two core product lines: oil-immersed transformers and resin cast dry-type transformers. Rated capacity ranges from 30kVA to 20000kVA at 10kV/35kV, complying with GB & IEC 60076 standards. CEHO delivers reliable power solutions for solar & wind farms, municipal grids, industrial parks, commercial buildings and data centers.

Company Strength

Founded in 2016 with a 20,000 ㎡ factory, CEHO independently manufactures core components including cores, windings and enclosures without outsourcing. Every unit undergoes a full test sequence: withstand voltage, temperature rise, partial discharge and short-circuit test. CEHO products have served over 1,000 power projects across 50+ countries. We supply standalone transformers or complete packages with compact substations, HV/LV switchgears and current/voltage transformers. Services include site survey, engineering design, factory witness test, installation guidance and lifetime technical support. Full tender & international certification documents are available, with customized designs for harsh environments in Southeast Asia, the Middle East and Africa.

Oil-Immersed Transformers S11-M / S13-M / S22-M Series

Ideal for outdoor heavy-duty applications: pole-mounted transformers, prefabricated compact substations, mines, ports and renewable energy booster stations. Designed with fully sealed corrugated tank & vacuum oil filling to block moisture and reduce leakage. High-grade silicon steel or amorphous alloy optional; S22-M reaches Class 1 high efficiency with low no-load loss to cut long-term energy cost. Oil convection cooling enables strong overload capacity to handle motor starting surge and fluctuating renewable loads. Standard fittings include pressure relief valve, temperature controller and oil level indicator; Buchholz relay and online DGA monitoring optional. Proven stable in high-temperature dusty, coastal salt-spray and high-altitude regions. It delivers outstanding economic advantage for large-capacity projects with simple maintenance and easily available spare parts.

Resin Cast Dry-Type Transformers SCB14/SCB18/SCBH15 Series

Preferred for indoor & underground substations, hospitals, schools, shopping malls, high-rises and data centers with strict fire safety requirements. Vacuum epoxy cast windings, non-flammable, explosion-proof and oil-free, complying with indoor fire codes. No regular oil maintenance or oil sampling required. Equipped with temperature controller, cooling fans and protective enclosure (IP20/IP30 optional), supporting remote temperature alarm for unattended power rooms. Low partial discharge, quiet operation and compact footprint to save room space. Natural air cooling (AN) / forced air cooling (AF) dual mode, temporary overload permitted under AF. SCBH15 amorphous version features ultra-low no-load loss, perfect for 24/7 continuous power supply, standard vector group Dyn11.

Selection Guide
